It is a further object to provide given passageway through the actuatingmeans means of actuating the valve without permitting the escape of thegases controlled thereby.

Referring The figure is a section tothe drawings:

through a gas line and the valve mechanism.

Referring to the drawings in detail, 1 1s a tubular member having apassageway therethrough designated cates with a pipe linefor be conveyedthrough sageway 2 communicates the valve.

2, which communithe gas which is to This paswith a valve chamber 3beneath a corrugated diaphragm 4 which is held between the top of thevalve body 1 and the cap 5, the cap either being threaded on the valvemember 1 or welded thereto at 6. This diaphragm carries centrallythereof a actuating screw ball is seated upon 8 carried tom, of thechamber 3 and at 10 which communicates with the passageway other slde ofthe line in ball 7 directly beneath an in the cap 5. This a valve seat 9in the botthe top of the which the valve is interposed. Pipes are joinedby sleeves on the threaded portion 1]. of the valve body 1.

It will be observed that through the passageways the gases may pass ingupon the position of the ball 7 .This

ball can be either relieved so that the gas may pass beneath the ball 7allowing it to go through the passageway into the passageway seated bythe screw 10 and chamber 3 2, or the ball may be 8. In either event, the

metal diaphragm 4 prevents the escape of gas into the upper chambphr'agm 4.

It will be understood that I desire to comprehend within my inventionsuch modifications as may be necessary toadapt it to varyin conditionsand uses.

I Iaving thus fully described my invention, what I claim as new anddesire to secure by Letters Patent, is: e

1. In a valve, a valve body having a passageway therethrough, a valvemember adapted to control said passageway, a diaphragm associated withsaid valve member and said passageway interposed between the valvemember and its actuating means, and an actuating means for said valvemember, separable from said diaphragm and valve member said diaphragmbeing corrugated, said valve member tioned by one of the corrugations ofsaid diaphragm. w

2. In a valve, a valve body having a passageway therethrough, a valvemember adapted to control said passageway, a dia- 70 phragm associatedwith said valve member and said passageway interposed between the valvemember and its actuating means, and an actuating means for said valvemember, separable from said diaphragm and valve 7 member said diaphragmbeing corrugated, said valve member consisting of a ball seated in oneof said corrugations, and adapted to be seated on its other side in avalve seat in 0 CHARLES P.
